Communication technologies including smartphones and laptops could now be 1,000 times faster

Many of the communication tools of today rely on the function of light or, more specifically, on applying information to a light wave. Up until now, studies on electronic and optical devices with materials that are the foundations of modern electronics -- such as radio, TV, and computers -- have generally relied on nonlinear optical effects, producing devices whose bandwidth has been limited to the gigahertz (GHz) frequency region. (Hertz stands for cycles per second of a periodic phenomenon, in this case 1billion cycles).

All-carbon-nanotube transistor can be crumpled like a piece of paper

(PhysOrg.com) -- Thanks to the flexible yet robust properties of carbon nanotubes, researchers have previously fabricated transistors that can be rolled, folded, and stretched. Now a team from Japan has made an all-carbon-nanotube transistor that can be crumpled like a piece of paper without degradation of its electrical properties. The new transistor is the most bendable reported to date that doesn’t experience a loss in performance.

Oxford Nanopore announces groundbreaking GridION and MinION gene sequencers

(PhysOrg.com) -- Oxford University spinoff company, Oxford Nonopore has announced at this year’s Advances in Genome Biology and Technology conference in Florida, two new machines for sequencing genes. Of particular note is the MinION, a machine small enough to fit in the hand which can be plugged into a laptop’s USB port. The other, the GridION, is a larger version that can be stacked to increase processing power. Both rely on a technology known as strand sequencing whereby a nanopore (engineered protein) is used to pull strands of DNA through a hole where a microchip measures minute changes in the electrical current in the membrane around it as individual bases, or pairs are pulled through. Because of the way it is done, much longer sections of DNA can be examined at once, doing away with the need to examine small sections independently and then knitting the results together with a computer afterwards.

Researchers build first physical 'metatronic' circuit

(PhysOrg.com) -- The technological world of the 21st century owes a tremendous amount to advances in electrical engineering, specifically, the ability to finely control the flow of electrical charges using increasingly small and complicated circuits. And while those electrical advances continue to race ahead, researchers at the University of Pennsylvania are pushing circuitry forward in a different way, by replacing electricity with light.

Space elevator by 2050 planned, to include space solar power

Obayashi Corp., headquartered in Tokyo, has unveiled a project to build a space elevator by the year 2050 that would transport passengers to a station 36,000

Ocean supremacy: the world’s largest “eco” super-yacht

Traditionally, a super-yacht is a vast, luxurious vessel where its opulence is only matched by its fuel consumption. However recently, the super wealthy have been making an attempt to show their green credentials by purchasing greener and more efficient ships. Sauter Carbon Offset Design (SCOD) have not set the standard by which all other green super-yachts will now be measured with the 42m Ocean Supremacy - the largest, greenest super-yacht in the world.

Electrical engineers build 'no-waste' laser

A team of University of California, San Diego researchers has built the smallest room-temperature nanolaser to date, as well as an even more startling device: a highly efficient, "thresholdless" laser that funnels all its photons into lasing, without any waste.
